The Xiaomi Poco X3 NFC (codename: surya) is a recently launched device which means it is all set to receive the upcoming Android 11 update officially but it may take some time to come. So, if you’re also one of the Poco X3 NFC users and want to flash the latest Android 11 based AOSP ROM then check this guide on how to install Lineage OS 18 on Xiaomi Poco X3 NFC over Android 11.
Needless to say that due to the Android’s open-source nature, most of the third-party ROM developers and even the Android users are always looking for unlimited possibilities to easily flash the custom firmware. Lineage OS is no exception here and you’ll be glad to hear that you’ll be able to customize the whole UI, lock screen, icons, fonts, themes, notification bar, navigation bar, launcher, etc apart from using the rooted apps (You can also install Root after flashing the Lineage OS on your device).
It’s also worth mentioning that you have to unlock the device bootloader first as all the Android devices do come with a locked bootloader from its manufacturer out of the box. Once you unlocked your device bootloader, you’ll be free to customize, install custom firmware, custom modules, enable root access, and more on your Android device without any limitation. Whereas Google has also uploaded the Android 11 Source Code to AOSP so that the custom firmware developers can easily build their third-party ROM for compatible devices.
Lineage OS 18 Features
LineageOS is a free, community-built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device. LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community.
It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restores the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
As mentioned, among all the aftermarket firmware, Lineage OS is the best one when it comes to performance, stability, and fully-featured Custom ROM. Thanks to XDA Senior Member mahajant99 and the Lineage OS Team for this latest ROM.

How to Install Lineage OS 18 on Xiaomi Poco X3 NFC (Android 11)
The installation is pretty simple and easy. If you have installed any custom ROM before then you will have no issue flashing the ROM as the process is exactly the same. But before proceeding to the installation let me clear that this build is in the very early stage which means there will be bugs and many functions may not work properly. So, we do recommend not to flash the ROM on your primary device.
- RIL (Calls, SMS, Data)
- IR camera
- Video Playback
- Inform the developer if you find any
- Enable USB Debugging on your Xiaomi Poco X3 NFC. Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.
- Also, enable the OEM Unlock from the Developer Options.
- Make sure the bootloader on your device is unlocked and your device is rooted and you have a custom recovery installed.
- Make sure your device has more than 50% battery.
- Make sure you have taken a backup of your important data. Now proceed to install Lineage OS 18 ROM (Android 11) on your Xiaomi Poco X3 NFC device.
- Make sure that you have installed TWRP recovery on your Android device.
